I looked at CVS and Walmart for the Dr. Scholls kit that has the liquid and the pads… nothing. Of course at Walmart there are 2 people already in my way in front of the section. When get home I’ll start soaking it and then hit it with the sanding stone from my dremel. Wife has a fit if I use any of here 13,000 files amd stones she has. Even though she goes to have her nails done.
